为完善保护性耕作技术,在半干旱地区气候条件下,以玉米品种先玉335为试验材料,研究常规垄作、灭茬平作对耕层土壤水分状况、地温状况和玉米发育及产量的影响。结果表明：常规垄作促进玉米生长发育,提高苗期地温,灭茬平作土壤含水量高于常规垄作,灭茬平作处理比常规垄作处理增产3.6%。

To perfect the conservation tillage technology,the maize cultivar Xianyu335 was used as experimental materials to study the effect of conventional ridge planting and flat planting of crushing stubble on soil moisture,tilth temperature and growth and yield of maize in semiarid region.The results showed that the growth and development process of maize was promoted,as well as tilth temperature was increased by conventional ridge planting.The average soil moisture content of flat planting of crushing stubble was higher than conventional ridge planting.The yield of flat planting of crushing stubble increased by 3.6% compared with conventional ridge planting.
